Big Idea : Many important practical and mathematical applications involve comparing quantities of one kind or another; it is important to know which method to use and how we should use them. Essential Question: What methods are there for comparing things?
Notes from class:
2/3 = 80/120 1/4 = 30/120
4/8 = 60/120 3/5 = 72/120
A. Which recipe will make juice that is the most "orangey"? Explain your answer.
Mix A would make the most orangey because it has the more concentrate than the water between different mix.
B. Which recipe will make the juice the least "orangey"? Explain your answer.
Mix B would make the least orangey because it has the least concentrate mixed with water than the other mix.
C. Assume that each camper will get 1/2 cup of juice. For each recipe, how much concentrate and water are needed to make juice for 240 campers? Explain your answer.
Mix A Mix B Mix C Mix D
C: 48 C: 24 C:40 C:45
W:72 W: 96 W:80 W:75

1. How did you use ratios in solving Problem 3.1?
In 3.1 A and B I used ratios to compare the concentrates.
In question letter C. I used comparison to see the difference in amount of concentrates and water.
2. For each recipe, how much concentrate and how much water is needed to make 1 cup of juice?
Mix A Mix B Mix C Mix D
C:3/5 C:1/5 C:4/12 C:3/8
W:1/5 W:4/5 W:8/12 W:5/8
